The nose of the star-nosed mole Condylura cristata is a complex biological novelty consisting of 22 epidermal appendages. How did this new set of facial appendages arise? Recent studies find remarkable conservation of the genes expressed during appendage formation across phyla, suggesting that the basic mechanisms for appendage development are ancient. In the nose of these moles, however, we fi...

Two species, Oecetis furva and Orthotrichia tragetti, are recorded for the first time in Croatia. Moreover, O. tragetti is recorded for the first time in the limno-ecoregion Hungarian Lowlands (ER11). Adult caddisflies were collected from 2010 to 2012 in Kopački rit Nature Park. Sampling was conducted using light traps (15 W UV lamp) that were operated monthly, with the exception of May when tw...

Of the aspidogastrids Multicalyx cristata, Lobatostoma ringens, Cotylogaster basiri, and C. dinosoides sp. n., the last two had not been previously known from the Gulf of Mexico. The latter differs from other members of its genus by having relatively large equatorial marginal alveoli in comparison to those at the anterior and posterior ends of the holdfast. It also possesses extensive transvers...
